GENERAL DESCRIPTION

The AD9222 is an octal, 12-bit, 40/50/65 MSPS analog-todigital converter (ADC) with an on-chip sample-and-hold circuit designed for low cost, low power, small size, and ease of use. The product operates at a conversion rate of up to 65 MSPS and is optimized for outstanding dynamic performance and low power in applications where a small package size is critical.
